Dashlane has the stronger cryptographic foundation — Argon2id by default, closed server. Bitwarden has the stronger transparency posture — open source server and clients, self-hosting available. The security scores reflect this: Dashlane 9.0 vs Bitwarden 7.9. The transparency scores reverse it: Bitwarden 8.6 vs Dashlane 7.0.

What you get that Dashlane doesn't offer

Open source server and client code — independently auditable by anyone. Self-hosting for users who want their vault off third-party infrastructure. Emergency access for account recovery delegation.

Substantially better value: unlimited free tier across devices, paid plan significantly cheaper than Dashlane.

What you give up

Dashlane's crypto stack is technically stronger — Argon2id enabled by default, no manual configuration needed. Dashlane bundles a VPN and covers more features in the base plan. Autofill reliability score: Dashlane 4.6 vs Bitwarden 6.6 — both have friction, Bitwarden less.

What you get that Bitwarden doesn't offer

The strongest cryptographic foundation in the category — Argon2id by default, end-to-end encryption on all fields. VPN bundled in the paid plan. The broadest feature set (9.5 vs 7.9) — passkey support, dark web monitoring, secure sharing — without add-ons.

What you give up

Server code is closed — you trust Dashlane's implementation. No self-hosting. No emergency access. Dashlane's audit record has gaps: last published audit was 2021.
